What is an audiogram?
An audiogram is a graphical representation of a person's hearing ability, typically obtained through a diagnostic test called audiometry. The audiogram charts the softest sounds a person can hear at different frequencies, usually measured in Hertz (Hz). The vertical axis of the graph represents intensity or loudness, while the horizontal axis represents frequencies or pitch. During an audiometric test, the individual wears headphones and responds to various tones presented at different frequencies and volumes. The audiologist records the lowest level of sound the person can detect at each frequency, creating a comprehensive audiogram. This tool is crucial for assessing and diagnosing hearing loss, as it provides a detailed profile of an individual's hearing thresholds across the audible spectrum.
